INTERNAL-COMBUSTION ENGINE.

' Application filed February '9, leaopserial No. 357,244. renewed April 15, 1924.

This invention relatestoginternal combustion engines, more especially to means for readily starting the same, preferably auto- 1 to accumulatein such chamber, I use this i matically, particularly when the engine and" the surroundings are cold, it being amongthe objects ofthis invention to produce'a .de-f vice which is simple, reliable and easy to op erate. In carrying the obj ects ofmy nventlon into effect, I provlde a. source'of gaseous fuel,

preferably in theiform of a chamber in or above the liquid fuel tank of the engine to allow the vapors and fixed gases therefrom gaseous fuel for starting the engine and .1 contemplate modifying my device so as to utilize fixed gas from any independent source, and I may use any fluid fuel for the engine. .The gas chamber is directly connected inder. w V Referring to the accompanying drawings forming a part hereof and in which similar reference characters-denote similar parts, Figure 1 illustrates my invention as applied to asingle cylinder engine.

Figure 2, a detail *cross sectional view of the gas chamber, and Figure 3 shows a diagrammaticview of the connections from the compressed air re- ;ceptacle to the engine.

:The engine 1 carriesthe ordinary intake manifold 2 and exhaust manifold 3.

liquid fuel tank'l is connected to the intake manifold 2 by fuel pipe 5 andcarbureter or mixer 6 having air intake openings 7 I- generally provide athrottle governorto control either the airor" the explosive mixture entering the engine.

At the'top of the tank 11 fix a chamber 8 preferably dome-shapedhaving a-perforated extension 9 extending into the, tank I and an opening 10 in the lower-portion of extension 9 into which is fitted fuel supply pipe 1 1 through which fuel or liquid is entered into the tank and the enter end of said pipe is closed by cap 12 havlng a breather opening as usual. The top offuel pipe 11 is placed in such a relation to the top 14 of; the fuel tank i that the highest level 18 of liquid in the'tank will be a considerable distance below the top 14 of the tank.

At or near the top of dome 8 is a valve 15 seated in valve casing 16 and has a stem 17 directed preferably upwards, the end of the to the intake port of theengine cylstem carrying a piston 18operating in cyl- Inder 20 and closely fitting the walls thereof,

a spring being provided to normally force valve 15 intoclosed positionQflA pipe 21 is provided toallow fluid pressure tobear on plston 18 to open the valve. A pipe 22 con-- valve 15 maybe used, p

The above improvement is part of a sys: tem which I have developed which is capablev of starting an internal combustion engine carrying an electric generator without theme of batteries In orderto accomplish this I provide an air compressor or turbine (not shown) which is attached t'o the engine andto a source of compressed air, prefer ably a tank. Suitable pipes and valves are arranged so that when it is desired to start the engine a valve is opened by hand allow.-v ing air from the compressed air tank to flow into the-compressor which will operate the compressor and impart rotating action to the engine. At the same time the compressed 2. .Any other suitable means for controlling air is introduced into the compressor or turbine a suliicient amount of compressedair is entered in the pipe 21 and onto the piston The compressor or turbine is so arranged that itwill continue to operate after theen- 'gine'is started and pump air into the com-' pressed air tank until it is fully charged when the compressor is automatically cut off, thehand valve being manually closed which will cut-0E the air from the tank'to the turbine and to the pipe21.

, The means .for turning over the engine and 'forgsimultaneously, operating valve. 15 I .7 V

are shown diagrammatically in Figure'S and x.

include a compressed air tank 23, a pipe 21 leading therefrom to the valve, 15, a'valve 24 Tin said pipe and a pair of pipes25 and 26 leading to the compressor 27 which includes aturbine wheelon thevengine shaft. A twoway valve 28, when turned in one direction,

admits compressed air to thepipes 21 and 25- and when turned in the other opens the Y way from pipe 26 to the tank so-that the proper degree of compression "may bereestablished in the tank. I H
